She was my half sister from my dad's first marriage. We were close when we were younger and she did really go out of her way to have a relationship with me at that point. I imagine her and my dad had some conflict, which I would understand if she could just be honest with me about it. I'm no longer living there, yet I've only seen my nieces twice. She gave me a hug last time and said, "Let's not make it another four years." I've reached out a couple times but nothing came of it. It's now been six years since I've seen them and they only live an hour away. It goes back to the "I don't need anyone in my life that doesn't need me" thing. As much as I'd love to see my nieces, I've had a life's worth of heartbreak over this and just can't deal with putting myself out there anymore.
